Hollywood brides

Agron, 30, and the folk rock musician were first romantically linked in the summer of 2015, when they were spotted holding hands during a stroll in Paris.

They continued to make public appearances together in the months leading up to their engagement, and a source tells Us Weekly that the pair's relationship remains in perfect harmony.

Agron starred as the head cheerleader on “Glee.”

"He is the nicest guy and treats her like a princess," the insider said. "He is so thoughtful and flies her family everywhere they go and to see them whenever she wants. He is also so good to her friends."

Agron rose to fame on "Glee" for her portrayal of Quinn Fabray, the head of the cheerleading team at the show's William McKinley High School.

Before becoming involved with Agron, Marshall was once linked to pop superstar Katy Perry, according to Us Weekly.
